SELECTING PERIPHERAL EQUIPMENT
11.9.3 Function Specifications
■ Terminal functions (unit type)
Connect to a three-phase power supply via a dedicated reactor.
Connect to inverter power supply input terminals P(+) and N(-).
Grounding terminal for converter chassis (case)
Control power auxiliary input
Connect to the control power supply backup terminal, same power
supply system as the main circuit power supply.
This is the connection terminal for the fan power supply. Connected with
R1-Ri and T1-Ti shorted when shipped. If using the fan power supply
independently, consult your Fuji Electric representative.
Synchronous power supply input
for voltage detection
This is a detection terminal used for the control inside the converter, and
is connected to the dedicated reactor and dedicated filter power supply
side.
R, T, R2, T2 *1
(when equipped with option
card)
Input for control monitoring
This is a connection terminal for detecting blown AC fuses.
Converter runs when ON across RUN and CM, and stops when OFF.
By eliminating the cause of the alarm when an alarm stoppage occurs,
and turning ON between RST and CM, the protective function that was
activated is canceled, and operation resumes.
0: External alarm [THR], 1: Current limiting cancel [LMT_CCL],
2: 73 answerback [73ANS], 3: Current limiting switch [I-LIM],
4-13: Custom Di1-10 [C-DI1 to C-DI10],
14: Universal DI [U-DI], 15: AC fuse blown [ACF],
16: RHF overheating alarm [RHF-OH],
17: Parallel system cancel [MT-CCL]
18: Generator/commercial power supply switching [SW-GEN]
This is a common terminal for digital input signals.
Connect the power supply for PLC output signals. (Rated voltage: 24 V
(22 to 27) DC)
A signal is output when the converter protective function activates and
an alarm stoppage occurs.
(Contact: 1C, when error occurs, across 30A-30C: ON)
(Contact capacity: 250 VAC, 50 mA max.)

This is a common terminal for analog output signals.
Charging resistance ON relay
output
This is the control output for the external charging resistance ON relay
(73).
*1: To use the AC blown fuse detection function, the OPC-RHCE-ACF card for AC blown fuse detection is required.
Refer to the RHC-E Unit Type Instruction Manual for details.
